Tiny Horrible Xen -- hey! THX -- that was an accident!

Sorry.

Tiny Horrible Xen -- THX -- is a minimal -- BTW, only in the linux
world can you call this minimal:
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/hda4             12405032    440620  11334264   4% /xentest

Sorry.

Tiny Horrible Xen -- THX -- is a thing Aki and I cooked up, using
Richard Miller's port of Plan 9 to Xen 3. It is a minimal disk image
with a minimal linux and minimal X11. It boots in a few seconds,
direct to a /bin/bash prompt, since we don't run any linux shi --er,
scripts. It has all the modules we can find compiled for it. It mounts
ramfs over the writeable places -- /var/tmp, /tmp, etc. -- so the disk
footprint will not grow. It does not yet run root read-only.

Anyway, it has all the modules. It boots to a bash prompt, running one
bash on each of 6 VTs. The goal is to use Linux as a huge driver layer
for Plan 9, and have Linux do nothing else. We provide a native
drawterm that runs in /dev/fb (thanks aki!). VNC works. we have the
plan9ports rio on the linux side in /usr/bin. Xvnc works. So you can
run an X desktop in a vnc window that looks like X. In all ways,
linux, running as domain 0, is intended to be subordinate to Plan 9.

You can't run native X11, since we don't provide those servers, This
is intentional.

The Plan 9 boots as a terminal and gets root from Somewhere On The
Net. I use 9grid.net. I need to learn how to use CFS.

Users wanted.
